The impact of the coronavirus disease 19 (COVID-19) pandemic on health care workers has been substantial. However, the impact on vascular surgery (VS) trainees has not yet been determined. The goals of our study were to gauge the impact of COVID-19 on VS trainees' personal and professional life and to assess stressors, coping, and support structures involved in these trainees' response to the COVID-19 pandemic. ⋯ The pandemic has had significant impact on VS trainees. Trainees reported significant changes to clinical responsibilities, exposure to COVID-19, and pandemic-related stressors but demonstrated healthy coping mechanisms with low self-reported anxiety levels. The VS community should maintain awareness of the impact of the pandemic on the professional and personal development of surgeons in training. We recommend adaptive evolution in training to accommodate the changing learning environment for trainees.

Antegrade superficial femoral artery (SFA) access for peripheral artery disease reduces the time, radiation, and contrast required with contralateral common femoral access (CFA). Yet, this technique remains underutilized in the treatment of SFA, popliteal and tibial disease, and there remains limited data on the safety and effectiveness of antegrade SFA access in the outpatient setting. ⋯ Percutaneous antegrade SFA access can be performed safely in the outpatient setting and remains an effective alternative to retrograde CFA access with significantly less utilization of fluoroscopy and contrast.

Extracorporeal membrane oxygenation (ECMO) has become an accepted treatment modality in the management of select patients with cardiopulmonary failure. As a result, its use has increased significantly over the past decade. However, the effect of complications on mortality is not clearly established. We performed a comprehensive, up-to-date meta-analysis of peer-reviewed literature focusing on the effect of vascular complications (VCs) on the survival of patients receiving venoarterial ECMO (VA-ECMO) with femoral cannulation. ⋯ The most recently available data published in the literature demonstrate a significant correlation of VCs with mortality. Therefore, aggressive attempts should be made to minimize VCs in patients with femoral VA-ECMO cannulation.

The ability to salvage the mangled lower extremity is both technically challenging and time consuming. It requires the collaborative efforts among multiple surgical specialties in addition to comprehensive post-traumatic wound follow-up. Our institution has integrated a dynamic effort among these specialists in the planning and facilitating a successful limb salvage program with creation of a mangled extremity algorithm. An integral part in this process is the vascular inflow to prepare coverage for large tissue defects lacking adequate recipient targets. Utilization of long saphenous arteriovenous (AV) loop has been cited with minimal data available using larger inflow vessels in the acute trauma setting. We performed a retrospective review and describe our early experience using our protocol with AV loop creation with free flap reconstruction to salvage traumatic leg injuries. Using the data, we sought to develop a mangled extremity protocol for trauma centers to guide mangled limb salvage. ⋯ Although a small patient cohort, utilization of long saphenous vein AV loop is successful as a bridge to free flap transfer for isolated mangled lower extremities. Development and incorporation of our mangled extremity protocol to guide limb salvage has proven successful in our early experience. Long-term data need to be complied to assess patency of the free flap transfer and quality of life outcomes.

Observational Study
The Interplay between Preoperative Anemia and Postoperative Blood Transfusion on Survival following Fenestrated Aortic Aneurysm Repair.
Anemia is associated with a higher mortality following standard endovascular aortic repair (EVAR). This study evaluates the impact of anemia on fenestrated endovascular aneurysm repair (FEVAR) for complex aneurysm (AAA) repair. ⋯ Anemia appears to be associated with an increased rate of postoperative MI, LOS, frequency of blood transfusion, and mortality rate following FEVAR but this surpassed by postoperative blood transfusion. Optimization of preoperative Hb should be considered as a potential target for improvements in clinical outcomes and hypothetically a consequential reduction in postoperative red blood cell transfusion need.
